Application filed June 30, 1905. Serial No. 267,684.

To @ZZ whom it may concerns Be it known that I, WILLIAM H. CARR, ofMeridian, in the county of Cayuga, in the State of New York, haveinvented new and useful Improvements in Adjustable Head and Back Rests,of which the following, taken in connection with the accompanyingdrawings, is a full, clear, and exact description.

This invention relates to adjustable head and back rests applied toinvalid-beds for the purpose of supporting the occupant of the bed inany desired reclined posture.

The object of the invention is to provide a head and back rests which shall be simple and inexpensive in construction and convenient andefficient in operation; and to that end the invention consists in theimproved construction and combination of the component parts of the headand back rest hereinafter described and as illustrated in theaccompanying drawings, in which` Figure l is an isometric perspectiveview of a head and back rest embodying my invention. Fig. 2 is afragmentary longitudinal section of the same. Fig. 3 is a detached sideview of some of the component parts of the invention. Fig. 4 is anenlarged perspective View of the bar which carries the supportingslatsof the head and back rest, and Fig. 5 is an enlarged transverse sectionon line X Xin Fig. 1.

represents the frame of an iron bedstead, the rails of which are usuallyformed of angleiron. b represents a shaft consisting of a square bardisposed across the under side of the side rails of .said frame andpassing through square holes in cylindrical collars b, which aresupported upon bolts o o, connected to brackets p, suspended from theside rails, as shown in Fig. 5. 4

c c are arms which are provided at one end with a square hole by whichthey are connected to the ends of the shaft t.

b2 represents a lling-block applied to the side rail at the attachmentof the brackets p p.

d denotes a flat bar which extends across the bed and has its endsformed in the shape of ears d3 cl3, Which abut on the sides of the armsc c and are adjustably clamped thereon by means of bolts d2 passingthrough holes c2 in the free ends of the arms and holes in the ears dand provided with heads and nuts.

f f are slats which are mounted transversely of the bar d and firmlysecured thereto by rivets or other suitable means.

g represents a lever which is provided with a square orifice g toreceive the correspondingly-shaped end of the shaft t. By means of thislever the shaft can be turned to set the arms c c in different angles ofinclinations as may be desired by the occupant of the bed. Suitablelocking devices are employed to retain the lever in its adjustedposition. A simple means for accomplishing this consists of a chain h,suitably connected to the frame a and receiving through one of its linksthe end of the lever, as represented in Fig. 1 of the drawings.

i denotes the wire woven bed-spring, upon which is placed the mattressfm, as indicated in dotted lines in Fig. 2.

In order to allow the bar d to rest upon the spring 'i when the arms c care in their lowered position, I form the bar with offsets j, so as tocause the main portion of said bar to be disposed in a lower plane thanthe end portions thereof.

A secondary adjustment of the slats ff is effected by loosening one orboth of the attaching-nuts on the ends of the bar d and turning the saidbar so as to impart more orless inclination to the slats, and bysubsequently tightening the nuts the bar d becomes rigidly set on thearms c c, and thus the slats are retained in their adjusted position.

To allow the described head and back rests to be applied to beds ofdifferent widths, I provide a bar d, which is adjustable in length. Forthis purpose I form the said bar of longitudinal sections d d, splicedadjustably end to end, preferably by forming said sections of sufficientlengths to cause their ends to lap one upon the other and clampedtogether by means of a suitable clip or band Z, embracing the lappingportions and provided with a setscrew l, by which to tighten said clipon the bar.

What I claim as my invention is` l. The combination, with the bed-frame,of a transverse shaft pivoted to the side rails of said frame, armssecured to said shaft to move therewith, a transverse bar connected tothe free ends of said arms, slats mounted on said bar, and aleverconnected to the end of the shaft, as set forth.

2. The combination, with the bed-frame, of a transverse shaft pivoted tothe side rails of said frame, arms secured to the ends of said shaft tomove therewith and apertured at their free ends, a transverse barclamped adjustably on the arms, slats mounted on said bar, a leverconnected to the shaft, and means IOO IIO

for looking the lever adjustably in position, as l llat side of saidbar, a lever connected to the set forth. aforesaid shaft, and means foradjustably Io 3.
